I made this half scale Katana from steel, brass, paracord, and wood. I worked on it through out the course of two weeks with a cost of about $12 dollars. It's a Christmas gift for my son. I'm sure one day he'll use it to strike fear in his bills but for now it will be a cool display on his bookshelf. The blade is about 11" long. Overall length is 16".

It was the most fun I've had creating something. I'm the guy who has to read every plaque at every historical site. Throughout this build, while referencing several pictures and videos, I got to read something interesting about nearly every part of a Katana. It was also fun to pull metal working, wood working, and knot tying all into one project.  

Step 1: Project planning

How big is a Katana anyway? Apparently it varies by the height of the samurai. I knew I was going to use 1/2" flat bar so there was one dimension. With the help of ratios I figured out how long the blade should be if it's 1/2" wide. 

From there I got together some other materials. I wasn't sure what all I would end up using but I had this to start. 
<p>That is seriously beautiful, well done!</p>
<p>&quot;I'm sure one day he'll use it to strike fear in his bills but for now it will be a cool display on his bookshelf.&quot; Well said my friend. Great project and by far the coolest letter opener I have seen Lol.</p>
<p>This is a great project and write up! I always backed out of making swords because the steps would be too time consuming and the material and process costs would be high but this is a nice way to get into it in miniature and just learn the major steps and components.. A+</p>
<p>Mr. Bling, you are the King!</p>
<p>Pretty cool! Great detail work.</p>

Very nice, but I guess you didn't fancy forging one the traditional way. It would take forever:-)
Amazing, Your son is going to be ecstatic over this piece of Genuine Artistic Creation. What a replica! Can hardly tell the difference between a Picture of a Real Katana and this ... Actually what you have made here is a mimiture Katana ... it is so good and your skill level is extreamly high I consider this to be the real deal! Good Job!
Thanks for all those nice words. I had a good time making it.
So AWESOME! And really well documented! Great work, AGAIN!
Thanks Ms.Obscura!
Coolest. Dad. Ever. :)

Respect! Such craftsmanship you're sir
The groove on swords is to let the blood run down it
Amazing! Adopt me please?
Very well made instructable. The sword is awesome. I'm sure your son will appreciate it. A gift made from the heart. Thanks for sharing with us. PS I won't let your son know before Christmas.
Very impressive. I saw a samurai sword letter opener at the department store in Epcot's Japan. It was about half the size of yours but cost about $150 if I remember correctly. Cool project!
Awesome, as usual.
